代码没读懂,但是cnt可能超了5e5

为什么要加这个啊？
```cpp
for (int i = 1; i <= n; i ++)
for (int j = i + 1; j <= n; j ++) p = dist(i, j), add(i, j, p);
```

@[_6872_](/user/341353) for (int i = 1; i <= n; i ++)
for (int j = i + 1; j <= n; j ++) p = dist(i, j), add(i, j, p);去掉
再加个add（y,x,z）

看错题了吧？这和直线距离有啥关系

@[_6872_](/user/341353) if (t!=n-1){
printf("orz\n");
return 0;
}
